I need a subwoofer that will work well with the Purdy Creations (Sunfire CRM-2) speakers I have. My Polk pw111 sux. Went over to Best Buy yesterday and brought home a Klipsch SW-350. Not pleased at all with the sound, and the darn thing is made in China!!!! Sounds about the same to me as the Polk 111, boomy and not that solid base I'm looking for. That Klipsch is going back to BB today! Been thinking about the Sunfire True Subwoofers. They are costly, and before I make a decision need some input from anyone who might have one. Of course, as usual, I'm drawn the the most expensive model, the TS EQ12 Sig. TIA for any advise.
